The points are the displaying elements. At them the set properties are evaluated. Points serve as the leaves of Fib objects.
An empty point "point()" is possible. The empty point has no effect (all properties are lost). It can be used in combination with other elements (e. g. the if-element).
There are also points with an empty position vectors "point(())", these points create the background (e. g. the background color).
The properties of the point (e. g. color, sound and / or odor) are determined in the branch above the point with property elements.
